INTRODUCTION
Ectopic pregnancy generally recognized as prİmary or secondary. Primary ectopic pregnancy can occur as a result of the fertilized ova entering the peritoneal cavity and attaching to mesentery or abdominal viscera. On the other hand, secondary ectopic pregnancy may occur following trauma or rupture of the gravid uterus where the developing fetus is lost into the peritoneal cavity (5). Although secondary ectopic pregnancy has been reported occasionally in all domestic animals, the actual incidence in cats İs unknown (6, 8).
The present case represents secondary ec topic pregnancy occurred following the uterus rupturc in a cat. The difference from other ectopic pregnancy cases is presence of early pregnancy together with ectopic pregnancy about 6 months af ter uterine rupture.
MA TERIAL AND METHODS
A fifteen-month-old Angora cat was admitted to Emel'geney Service, Faculty of Veterinary Medicine, University of Ankara, which was suffering from inappetence and emesis. According to owner, six months prior to the admission she gave one kİtten bcing stilibom without supervision in her first Iitter, no further kittens were bom and no more straining efforts were made, but she was lethargic, listless and had uncommonly vomitus for two weeks following this delivery. The animal was not taken any medical treatment during this period and then it was appcared to be normaL. The cat mated three times fifteen days before admission to clinic for referral and she had inappetence, emesis and polydipsia twelve days af ter mating.
RESULTS
Patient's body temperature was 40.3°C. A CBC revealed only slight leukopenia and neutropenia. In abdominal palpation the firm

movable, spherical masses located in the middle portian of the abdomen was detected.
Abdominal ultrasonography was carried out in dorsal recumbency and obtained an echogenic square shaped mass in anechogenic sac c10se to the spleen (Fig. ı).

With the owner's consent, at surgery, the standard ventral mid-line laparatamy was made through the linea alba. When abdomen was opened, a mummified fetus covered by thin transparent membrane was noticed. This fetus quite firmly adhered to amentum
immediately posterior to the spleen. Exploration of the uterus was revealed that there had be en an early pregnancy (approximately fifteen days) and a sc ar on the right ham, proximal to the bifurcation. The placental membranes were connected with the surface of the uterine rupture and were not completely drop out of the uterus or into the abdaminal cavity. The embryonic enlargements being the sign of the early pregnancy were located bat h on the left ham and on the right ham just distal to the uterine rupture (Fig.2). Alsa, corpara lutea were observed on both ovaries. The peritoneal surface were normal and no gross evi dene e of generalized peritonitis. The mummified fetus was dissected gently and routine ovariohysterectomy was performed. The abdomen was irrigated several times with warm isotonic saline to remove as much debris as possible and the incision was closed in the usual way. Af ter removing the ovaries and uterine horns, the early pregnancy status was accurated by the observation of the implantation sites af ter the dissection of the distinct swellings on both horns of uterus. The cat recovered uneventfully.
The membranes which covered fetus were contained the light mucoidal fluid. The mummified fetus measured as
6.0
cm from crown to rump and mid-dorsal to mid-ventral dimensian was 2.5 cm (Fig.3).>", ,'c. !;,

SECONDARY ECTOPIC PREGNANCY IN AN ANGORA CAT
DlSCUSSION
Primary
and
secondary
ectopic
pregnancy
have been previously
reported
in
cats
(i,3, 4, 7, 9,
ıo).
The cause of ectopia of
the
fetuses
may
be
related
to
injury
or
traumatic
rupture
of
the
uterus
during
pregnancy
or to abnormal disposition
of the
ovum after its fertilization (2).
The
present
occurrence
probably
represents
a secondary
ectopic pregnancy
in
which the fetus dropped out of the uterus by
means of a tear in the uterine wall. The fetus
escaped
from uterus
into abdominal
cavity
following
uterine
rupture
underwent
mummification due to inadequate blood supply
(i, 4).
To determine the precise time and the
origin of the uterine rupture in this case were
impossible because the owner had been given
us insufficient
history. But, if it is take into
account of her suffering from inappetence and
emesis
immediately
after parturition
and of
litter dimensions
we could be suggested that
the rupture must have occurred the resuh of
abdominal trauma at the time of parturition.
The interesting point in this case was
the appearance
of discrete uterine swellings
that
represent
early
placental
development
after breeding
on both
hom
together
with
secondary
ectopic
pregnancy.
We have not
been observed whether the development of the
fetuses would continue until term or not, due
to perform the ovariohysterectomy
at surgery.
Also,
we
have
been
suggested
that
the
recurrence of inappetence
and vomitus again
six months later together with early pregnancy
would probably
be regard aseptic peritonitis
occurred by means of secretion leaking from
perforation point of uterine homo
